Abstract: In recent years, the commune of Savè has experienced rainfall accidents that have affected agricultural production in general and soybean production in particular. The aim of this article is to analyze the impact of rainfall events on soybean production in the commune of Savè. To achieve this objective, a methodological approach was adopted. It consisted of data collection (rainfall data over the period from 1987 to 2017 and soybean production data from 2003 to 2017), data processing and interpretation of the results. The results of this research show that the minimum yield was obtained in 2003 and 2017 (800 kg/ha), while the maximum was obtained in 2010 (1107 kg/ha). The correlation between rainfall and soybean yield revealed that annual rainfall alone does not explain soybean yield trends. Apart from rainfall, according to 90% of the growers surveyed, soil components, area sown, maintenance and temperature were identified as determining factors in soybean yields.
